## When to prefer this

Use this endpoint when you need real-time crowd-sourced probability estimates for macro, crypto, political, or AI events from Polymarket's live orderbooks, especially when you want implied Yes/No probabilities, volume context, and whale sentiment rather than just a news summary or analyst opinion.

## Known failure modes

- No matching Polymarket market found for the given topic keyword — returns empty or null results
- Stale or delayed orderbook data if Polymarket API is temporarily unavailable
- Ambiguous topic string matches multiple markets, returning multiple or low-confidence results
- Payment failure via x402 micropayment protocol blocks the request
- Rate limiting or timeout if the Polymarket upstream is slow
